Cosy Sheridan has been called “one of the era’s finest and most thoughtful singer-songwriters.” She first caught the attention of national folk audiences in 1992 when she won both the Kerrville Folk Festival’s NewSong Award and The Telluride Bluegrass Festival Troubadour Contest, and then released her critically acclaimed CD Quietly Led on Waterbug Records. Almost 20 years later she is one of the most respected touring musicians on the folk circuit as well as a favorite teacher at many adult music camps.

In honor of MLK Day, Taproot Theatre is offering 50 percent off tickets to “The Whipping Man” (use the code “MLK” at online check-out on Monday only). The show runs from March 27-April 27.

The Whipping Man is an evocative tale of loyalty, diversity and self-exploration. In Matthew Lopez’s highly acclaimed script, a Jewish Confederate soldier and two of his former slaves are left to observe Passover together in the wake of the Civil War, prompting the challenging examination and reconciliation of the past while revealing the fear and uncertainty of venturing into a new future. This is a poignant play that The New York Times experienced as, “Haunting, striking, and powerful” and will ask questions of faith, freedom and identity.

Metro buses will be on reduced schedules on Monday, and some buses will be rerouted downtown and in the Central District and Capitol Hill to accommodate holiday events. Check Metro’s Construction & Events page for more information on reroutes.
